Mine was a 2006 model, and if I recall a 24rb model. The water pump was not behind any access panel, just mounted to the wall, kind of found it by accident. You might try calling CrossRoads about its location

My 19rd has water pump located in passthrough storage under the front bed on the side opposite the entry door. There's a panel to the right of the storage door...take out a couple screws and there's the water pump....at least that's where it is on mine.
Thanks Tim - That is exactly where it was. Seems like a un-likely spot because you remove a large panel that is located right behind the water heater and in the storage compartment under the bed but there it was. Thanks Again! Mark
